Learned something today. Never really realized the benefit of propane fuel, I just figured people really used it because it's more easily available/cheaper. Only need to hear once that it's just more heat overall, and it clicked in my brain. Even in the "simpler" jobs, there is still so much to learn. Got to love low volume job shop work, keeps a man sane because it keeps him on his toes.

It's important to remember that the tips are different. I believe you can get acetylene tips to work with propane, but it's not worth bothering with afaik.

@mrklean93 Glad you learned something. If I remember correctly John told me he has a propane tip that is rated for ~500,000 BTU/hr. It's some serious heat! -Cameraman

Good point about needing to allow enough room for the galvanized coating on the threads so that the nuts will thread on. I bought a lot of galvanized 1/4-20 carriage bolts from Home Depot for a project and it was impossible to screw the nuts on (not galvanized nuts) until I took the time to run a die down each one. Was a lot of time consuming work.

You can also heat the threads with a torch and wire brush the excess galvanizing off. If the threads don't need galvanized you can brush on a product (I believe it is galvstop) that keeps the galvanize from the parts that you don't want the galvanizing to stick to.

Propane can't get as hot as acetylene because it has more hydrogen. While hydrogen produces more heat than carbon, it can't get as hot because the combustion product (H2+O =H2O water) doesn't form properly above 2000C/3600F. Acetylene has much more carbon than hydrogen and carbon exhaust (CO2) is much more stable. So acetylene has enough carbon to get past the point that hydrogen likes. But since it has little hydrogen, it doesn't produce as much heat.

@@HOWEES mostly the cost of buying tanks and getting them filled/exchanged. My local welding shop can fill the small tanks, but not the larger. Getting oxygen and using my existing propane tanks would be easier. I'm an engineers that likes to fix stuff. I can't justify spending too much just to play around.

Could you do that with round tubing and still keep its shape without distorting the tubing inside? Awesome work men.

No it will not work, I have even tried similar many years ago, filling with sand is not good either, best is to put a mandrel inside the tube at the bend point.

if the rod is small (1/2" or less) go by the inside of the bend, if larger go by the middle, cut and bend a test piece, then modify as needed.

I heard that too, I meant to say "We may be doing less and less with acetylene". Propane puts out more BTU s /Cubic Foot, but at a lower peak temperature.

Heat transferred = total energy. Peak temperature is different than energy transferred.
